A prime example of this shift is the transition of Kubernetes Service Account (KSA) tokens from long-lived, static tokens to ephemeral, automatically rotated tokens with OpenID Connect (OIDC)-compliant semantics. This advancement enables workloads to securely authenticate with external services without needing persistent secrets.However, one major gap remains: image pull authentication.
